Shock sensitivity is a comparative measure of the sensitivity to sudden compression (by impact or blast) of an explosive chemical compound. Determination of the shock sensitivity of a material intended for practical use is one important aspect of safety testing of explosives. A variety of tests and indices are in use, of which one of the more common is the Rotter Impact Test with results expressed as FoI (Figure of Insensitivity.) At least four other impact tests are in common use, while various "gap tests" are used to measure sensitivity to blast shock. Julius-Peters KG is a notable German company which manufactures testing apparatus for these tests.
Explosives using thermally expandable microspheres in a solid matrix
Explosives using thermally expandable microspheres (TEMs) in a solid matrix are disclosed that facilitate tunable changes in local density, porosity, and ultimately, shock sensitivity. Solid high explosive systems with “on demand” shock sensitivity may be created. A relatively small fraction (e.g., 1% or less) of TEMs may incorporated during the manufacturing process of the solid matrix explosive (e.g., polymer-bonded explosives (PBX), trinitrotoluene (TNT), etc.). The fraction of TEMs used to achieve the desired explosive properties will depend on the base explosive material to achieve the desired initiation sensitivity.
